Off of forend questions for a while, on to rear handguard identification questions...

Some of the current rear h/g repros are rather tall

I'd put it in place and if it's too tall just sand it down carefully so as not to go into the rivets. Problem then is it'll be glassy smooth...

If it is bare wood, wet it. Water will raise the grain.
If it has a finish, steam it over the tea kettle spout.
It wont be glassy smooth anymore.

And they just keep showing up. The rear was cracked, but it is already glued and clamped.

As always, curious about the markings.
